Environmental EVA Sponge Backer Backup Rods

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Soundproofing & Buoyancy: Designed with EVA sponge material for sound absorption and noise reduction, ideal for acoustic insulation in commercial spaces. The closed-cell foam structure also provides lightweight buoyancy for water activities like floating and swimming.
  • Multi-Purpose Construction: Features a circular pattern and customizable shapes (round, square, star) to serve both functional (backer rods for construction gaps) and recreational uses (pool noodle accessories, decorative floats).

Key features

  • 1. Eco-Friendly EVA Material Technology

    • With environmentally certified EVA foam, you can achieve durable soundproofing while reducing ecological impact. The closed-cell structure ensures resistance to moisture and corrosion, outperforming traditional foam materials*.

  • 2. Customizable Circular Design

    • With a circular pattern and precision molding/cutting services, you can effortlessly adapt the rods to fit acoustic panels, wall mounts, or custom installations, offering unmatched flexibility compared to rigid soundproofing solutions*.

  • 3. Superior Soundproofing Performance

    • With a high sound absorption coefficient (up to 0.8), you can reduce ambient noise by 30-40 dB in studios, offices, or home theaters, surpassing basic acoustic foams in effectiveness*.

  • 4. Versatile Scenario Solutions

    • Designed for both residential and commercial use, you can deploy these rods in home theaters, recording studios, or open-plan offices to create quieter, more focused environments without compromising on space or aesthetics.

  • 5. Certified Sustainability Standards

    • With ISO 14001 environmental certification, you can meet eco-friendly regulations and reduce carbon footprints, making it ideal for green building projects or corporate ESG initiatives*.
